When you install JUST the rubber seal, does it fit nicely without the glass?
Then, when you try to install the rubber and the windshield (like in the video) where exactly does it "get stuck"?

This is a crazy idea but could it be that there are points along the pinch weld that are "higher or lower" and NOT in the same 180 degree plane. ?
If you lay the windshield glass on top of the pinch weld does it rest fully on the pinch weld all the way around the window or are there some gaps?

Silly question: Was there a windshield already installed in this car when you bought it?

I know it's driving you nuts but, don't do anything rash as glass doesn't bend too easily.
